IMPROVEMENT IN TUBE-CLEANERS.

Specification formingpart of Letters Patent No. 200,278, dated February 12, 1878 applicationflled May 8, 1877.

To all whom it may concern:

Be it known that I, JosEPH S. GODEREY, of Leslie, in the county of Ingham and State of Michigan, have invented a new and Improved Boiler-Fine and Water-Pipe Cleaner; and I do hereby declare that the following is a full n and exact description of the same.

The nature of my invention consists in providing a flue or pipe cleaner, with the blades so set and self-adjustable as to freely pass by any imperfections that exists in the flue or pipe, either by expansion or contraction, or any imperfection that may be in the line or P1P6 To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a longitudinal elevation; Fig. 2, plan of the head-piece.

The springs B have formed upon them projections on which are placed pivoted cuttingblades set at an angle to the axis of the clean er. By this arrangement a free movement of the blades is obtained, and a greater' cuttin g-ed ge presented to the tube to be cleaned; at the same time an easy passage of the blades over any obstruction is accomplished, and any cavity in the tube reached and cleaned. The springs B are arched a portion of their length, near the middle and opposite the nut E, so that by moving the nut E it will expand the cleaner, or allow it to contract to fit the tube to be cleaned.

The Acenter screw-threaded rod D is constructed with a shoulder to rest against the end of springs B, and hold them in place, and extends up in center of cleaner to carry the nut E, and extends below the head-piece A, and is iiattened to receive a wrench for turning it to move the nut Epupgordown.

The cutting-blades CA are pivoted at or near the middle, so as to give as nearv the same pressure -as possible each side of the joint or hinge. 1

The head-piece A is constructed with holes to receive the ends of springs B, and to which can be attached a handle.

What I claim as my invention, and desir to secure by Letters Batent, is-` 1. In a tube-cleaner, a cutting-blade, piv oted at or near the middle, as and for the purpose set forth.

2. In a tube cleaner, the spiral cuttingblades, pivoted at or near the middle, and attached to adjustable springs, as and for the purpose set forth.

3.In a tube-cleaner, the springs B, having a portion of their length arched near the middle, in combination with a nut and screwthreaded rod for expanding the same, as and for the purpose set forth.

4. In a tube-cleaner the combination of the spiral cutting-blades pivoted at or near the middle to the springs B, the springs B arched a portion of their length near the middle, nut E, screw-threaded rod D,.and head-piece A, as and for the purpose set forth.
